Don't forget that when you sign a work contract in California, it says explicitly that your employer can get rid of you at any time (and they are certainly happy to exercise that right, especially in startups). This is legally true for any company here, no matter how different they are from the ones I've experienced.
Also don't forget that we live in a city where entire teams frequently get cut because they're deemed unnecessary by the new CEO of the day. This is the same city where when people (albeit not in the tech industry) go on strike because they don't get certain benefits promised to them in the past, they become almost universally hated by everyone.
The US is not exactly a reference when it comes to siding with workers in those matters.
I'm not saying that I treat work as a dull, impersonal affair, far from that. As I've said in another comment, I've happily socialized and made life long friends and partaken in office outings and activities in my life as a tech employee.
But I prefer to not cloud my mind with ultimately useless romantic notions such as "your work is your family" (I already have a family, and it's filling its role quite well- don't need another one). When the bad times come, it makes dealing with things much easier. And when employers try to push this angle a bit too much, it's a sign to me that the workplace might not be too desirable to be at.
And that there's an organization/group out there that treats it just like that.
It's sort of like jaded lovers. Certainly there are people that poo-poo the notion of "soul mates" or "love at first sight." Fair enough. But it's always a little bit sad when that dampens the mood for people who are caught up within potential romance, no?
Honestly, I'd rather spend time working for someone (or on something) that I believed in and make less money than the usual soul crushing 9 to 5 and make a boatload. I'm in that situation now, actually, and it's not great. I moved the the bay area earlier in the year to chase the almighty dollar, and my overall happiness level has gone down. Who'd have thought?
How do you know that's how it is? For most companies, "work is family" may be hyperbole, but how do you know it's that way at PA? I don't profess to know, but I don't find it unreasonable that there are companies out there that are different than the ones that I'm accustomed to. Just like I accept that there are people out there that have lives very different than how I've lived mine.
